The Met office has issued it’s first ever amber extreme heat warning as parts of the UK are set to reach 33 degrees C
he Met Office has issued its first ever “amber extreme heat warning” as parts of the UK are set to reach a sizzling 33C.
The warning – which is similar to those issued when heavy rain or snow is forecast – covers a large part of Wales, all of south-west England and parts of southern and central England, and will remain in force until the end of Thursday.
It comes after temperature records were set over the weekend.
Met Office forecaster Dan Stroud told the PA news agency: “This type of warning is issued when temperatures are unusually warm for a particular location, with the threshold different in certain areas of the country.
“Really it’s to raise awareness that extreme heat can have an impact on things like your wellbeing, power supply and transport so people should take action.
“Good things to do include staying out of the sun during the afternoon when it’s the hottest period of the day, closing curtains to keep living rooms cool, staying out direct sunlight and drinking plenty of water.”
Public Health England (PHE) also issued a heat-health alert, warning members of the public to take measures to stay cool and look out for vulnerable people.
In England on Sunday, 31.6C (88.88F) was recorded at Heathrow, overtaking Saturday’s record-breaking 30.3C (86.54F) recorded in Coton in the Elms, Derbyshire.
Wales recorded 30.2C (86.36F) in Cardiff, compared with 29.6C (85.28F) reached in Usk, Monmouthshire, on Saturday.
But forecasters said temperatures are expected to climb further early this week, possibly reaching 33C (91.4F) in some western areas, but widely high 20s and low 30s elsewhere.
The Met Office launched a new Extreme Heat National Severe Weather Warning at the start of June 2021, with warnings to be issued based on the impacts of extreme heat.
Amber and red warnings can now be issued to inform the public of potential widespread disruption and adverse health effects.
Forecasters said the amber warning comes as the forecast continues to signal for unusually high temperatures for western areas in particular, as well as continuing high nightime temperatures creating potential impacts for health.
Extreme heat can have health consequences, especially for those who are particularly vulnerable, and it can impact infrastructure, including transport and energy, as well as the wider business community.
Dr Owen Landeg, Scientific and Technical Lead at PHE, said: “Everybody can be affected by high temperatures and most people are aware of good health advice for coping with hot weather.
“However, it’s important to keep checking on those who are most vulnerable such as older people and those with heart or lung conditions.
“As we experience the first hot weather episode of the year, it’s important for everyone to remember to adapt their behaviours. This is particularly important during the pandemic with many people self-isolating.”
The Local Government Association, which represents councils in England, also said people should think carefully before travelling to beaches, parks and other public places.
During hot weather, there is often increased traffic near coastal areas, increased use of open water by the public, and an increase in wildfire risk.
Met Office chief operational meteorologist Steven Ramsdale said: “The high temperatures are going to continue through a large part of this week.
“Many areas will continue to reach heatwave thresholds but the amber extreme heat warning focusses on western areas where the most unusually high temperatures are likely to persist.
“There’s a continuing risk of isolated thundery downpours late in the afternoons but most areas will stay dry until later in the week.
“Temperatures should begin to fall for most areas heading into the weekend, with some more unsettled conditions looking to develop.”
Top ways to stay safe in the heat include drinking plenty of fluids and avoiding excess alcohol, keeping out of the sun between 11am to 3pm, walking in the shade, and applying sunscreen and wearing a wide-brimmed hat.
People are also urged to avoid physical exertion in the hottest parts of the day.
Chloe Brimicombe, a PhD heatwaves researcher at the University of Reading, said: “We’re likely to see increased hospital admissions over the next few days, due to heat stress – a build up of body heat as conditions prevent people from cooling down, even at night – and other heat-related health issues.
“Vulnerable people do die. Outdoor workers can get long-term kidney disease. We can also see a rise in air pollution, which affects people’s lungs.”
Dr Rob Thompson, a meteorologist at the University of Reading, said: “Heatwaves are one of the weather extremes that are most easily linked to climate change which is already affecting us here in the UK.
“British heatwaves are already hotter and last longer, compared to just a few decades ago.
“The hottest day of the year in the UK is on average nearly 1C warmer now than the average in the period of the 1960s to the 1980s, and extended spells of warm weather last more than double the length.
“We can expect that extreme summer heatwaves of the type that can kill people in the UK will become a regular occurrence, hitting us on average every other summer by the middle of the century, under current trends of increasing emissions and warming.”
London Ambulance Service has urged people to only call in the event of an emergency, and not to ring back asking for an estimated time of arrival.
It added this is due to it receiving a high number of calls and being “extremely busy”.
It is understood the high number of calls are due to the warmer weather, an increase in Covid-19 transmission rates and an increase in incidents as more people are out and about due to the lockdown easing.
Police said a body was recovered from a lake in Sheffield and a man died after falling from rocks in Dorset, taking the number of deaths linked to the warm weather on Sunday to five.
South Yorkshire Police said emergency services were called to Crookes Valley Park shortly after 7.30pm on Sunday following calls that a man had got into difficulty in a lake.
An underwater search team discovered a body in the water just before midnight, with formal identification yet to take place, the force added.
Elsewhere, Dorset Police said emergency services were called at 6.30pm on Sunday to reports that a man had fallen off rocks at Stair Hole near to Lulworth Cove in the Purbeck area.
The man was pronounced dead at the scene and his family have been informed, according to the force, which added that there were no suspicious circumstances.
Two teenagers died in Greater Manchester and Oxfordshire on Sunday, along with a man in his 50s in North Yorkshire.
The Met Office has also issued a yellow warning for thunderstorms on Monday evening in London and south east England.
Saturday had marked the hottest day of the year for all four nations, and the hottest day since records began for Northern Ireland with 31.2C (88.16F) recorded in Ballywatticock, in Co Down, beating the previous highest temperature of 30.8C (87.44F), which was reached on July 12 1983 and June 30 1976.

(CNN) — Few experiences herald the joys of summer living like eating and drinking outdoors, or dining al fresco as Italians call it, literally "in the open air."But when you've lived through what has felt, at times, like an endless lockdown -- or indeed been unable to dine out at all, for up to a year -- then the thought of eating on sun-dappled terraces, elegant lawns, waterside promenades or […]
